Abstract:
This work machine comprises: a plurality of booms that extend and contract by means of power of an actuator; a boom coupling pin which is supported by the booms, moves in the entering direction by means of a spring to turn into an entering state in which adjacent booms are coupled, and moves in the pulling direction by means of power of a motor to turn into a pulling state in which the coupling is released; and a manual operation member inserted into the boom coupling pin and disposed coaxially with the boom coupling pin. As the manual operation member rotates on the basis of the manual operation of an operator, the boom coupling pin moves in the pulling direction together with the manual operation member, and the coupling between adjacent booms is released.
